探究铁碳微电解法处理油田钻井废水

Discussion of Oilfield Drilling Wastewater Treatment by Iron-Carbon Micro-Electrolysis Technology

近年来,铁碳微电解法在废水处理领域得到了较好的应用。基于这种认识,本文以油田钻井废水为研究对象,开展了利用铁碳微电解法处理油田钻井废水的实验。实验结果表明,在铁碳比例为1:1、溶液pH值为3.2、铁碳投加量为0.8kg/L和150min的反应时间下,使用铁碳微电解法进行700mL油田钻井废水处理,能够使废水COD浓度由586.42mg/L降低至174.46mg/L,从而使废水中有机污染物得到有效去除。

Recently,the iron-carbon micro-electrolysis technology has a better application in the field of wastewater treatment,on which cognition,this paper has developed the experiment of making use of iron-carbon micro-electrolysis technology to process the oilfield drilling,wastewater.The result has shown that under the condition that iron-carbon proportion1:1,pH value of solution3.2,iron-carbon dosage0.8kg/L and reaction time150min,use the iron-carbon micro-electrolysis technology to take the700mL oilfield drilling wastewater treatment,which can reduce the wastewater COD concentration from586.42mg/L to174.46mg/L,so that to remove the organic pollutant in wastewater effectively.
